Attorneys vention is the-provision of an acetylene gas" generator, wherein the sludge may bejproperly cleaned and expelled therefrom when fncE'rYLnnneAs GENERATOR.

ments in acetylene gasgenerators, one ob- Ject of the invention being the tprovlsion 01 a generator ofsimple construction, in which the parts are arranged for ready accessi bility and for easy cleaning, there being pro-: vided a gas bell which ca'rries'bodily therewith a carbid holder and a sludge agitator,w

whereby theapparatus is made compact and easily cleaned. 1 v

A still further object of thepresent innecessary. a I a i 4 p 7 g a With the foregoing and other ob ectsfin' view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de scribed andcla'imed, it being understood 1 that changes in the precise embodiment of the invention herein disclosed can be made within the scopeof whatis claimed without departing from the spirit of the invention. 1n the drawings: Figure 1 is a vertical central sectional view through the complete generator; Fig. 2 is a perspective view upon alarger scale of the carbid outlet of the carbid holder or hopper with the adjacent partsthereof. I

Referring to the drawings, the numeral 1 designates the main receptacle which :isan open ended receptacle, and is provided with a sludge drain 2; A pressure relief pipe 3 having an extension 4 at the; lower end there of for receiving condensation is" provided and is led by the short pipe 5 and the vertical pipe 6 within the generator chamber 1, the inlet end 7 being projected to extend below the level of the water within the same so that no gas is permittedto;passthrough the pipe3. By this means anyun'due pressure within the generator will be relieved.

Disposed at a substantially diametrical point to the pipe 3 is the gas directing pipe 11, the inlet end 8 of which is disposed within the generating chamber andextended downwardly to receive'the generatedgas' to ERNEsrMQRQ EBAUGH, or LONG Berton, onro. 7

are

direct thesame through thevertical pipe 9 and the shorthorizontal pipe 10 which is seated within the wall of the chamber 1 to the 'outlet supplying pipe 11, there being Patented Get. 12, m n.

disposed a condensate receiving cap or pipe v 12'below the pipe 10 and in alinement with the pipe 11.

The bell 13 is disposed telescopically within the member l to be raised and lowered due to the increased and decreased volume of gas generated and is provided with a plurality'or" guiding eyes 1a in which are adapted tofit the rods 15, the upper ends of which are hooked as at 16 while the lower ends are connected to the blades 17' of the v sludge stirring member; Thus the sludge stirring member 17 remains substantially at the bottom of the generator'chamber 1 dur ing thelowering and elevatingof the bell 13, yetis in sucha position that when the bell isoscillated, the same will stir the water and the sludge within the water, so that the water and sludge may be drained through the valved outlet Connected to and carried by the sludge member 17 are the upright members 18 which carry the receptacle 19 provided with the foraminous or screen bottom This receptacle 19 is disposed concentrically of the bell and chamber 1 to receive the lump carbid as the same is dropped thereupon and as the receptacle 19 is disposed below the water level, the carbid is retained therein during saturation and disintegration due tothe effect of the water thereupon. 1

[An opening 21 is provided concentrically of-the bell 13 at the top thereof and, fitting a i thereunder is the funnel shaped end 22 which cooperates with the carbid receptacle 23. y The funnel is therefore disposed to project within the bell 18, the outlet endJQO being disposed concentrically above the cleaning member 19 so thatflthe carbid ejected therefrom willbe directed upon the screen bottom of themember 19. A 'filling opening 24 is -provide'ol in the top' of the receptacle 23 and is controlled by a screw plug 24:. i

A valve actuating rod 25isdisposed with in thecarbidholder 23 so that its upper end by means of the 'spring26 is held in engage ment' with the under side of the plug 24 which acts as a means for limiting the up ward movement of the rod, the removal'of the plug 24 permitting the rod to bemoved upwardly by thespring 26, Thus the piv- 'ote'd' closure'28 is, elevated and closes the spout 29 during the filling ofthe receptacle projecting thereabove and carrying the 23 with C2tIbld.' Then when the cap 24 is placed in vposition, the rod 25'is depressed and the closure 28 assumes the positionv as sleeve 32 for the reception of thestem'31' 'which is connected to the upper end of the r carbid receptacle 23, said stem 31 being apertured so that a pin (not shown) may be introduced throughany of the apertures above the frame 33 and thus lock the bell and the carbid receptaclein the desired elevated position duringthe removal of thecap 24 and the recharging of the carbid,

I holder 23.

In order to provide an aut'omaticineans forfeeding the carbldiromthe outlet-end of the spout, 291due, to the loweringof the V bell 18. and: toicut off the supply when the bell has been elevated-to the proper distance, a pin 35 forms a" pivot for the lugr fof the swinging meinberfiti, said member 36 being disposed to swing below and close the outlet 29 0f the funnel 22 when thebell 13 is at its, highest elevation or at its adjusted elevation. 'The lowering of the bell causes" the lower end ofthe rod 38 to engage the bottom of the receptacle 1 and thus depresses the'bladeend 37 of the member 36 to open the -outlet'29, the carbid therefrom being directed upon the blade 37 which: in turn directs the same to and upon the screen.

20 which holds the Vcarbid until dissolution;

As soon as the gas has been generated sufficlently due to the introductionof the carbid within the water of the'generator. the bell 13 is elevated and the rod 38 disenv gaged, from thelower end ofthereceptacle 1, so that the parts are in theposition as shown. In order to render this action of the cut oil member 36 adjustable, an extension end 39 is fitted upon the lower end of the rod ,38, the same, being preferably; screw threaded so asto'be readilyfadjustedwhen desired; t i

s A filling funnel F with outlet f is' provlded to permit water to be supplied to the casing 1. i I

The screen-20 in addition'to assisting in scattering the" carbid, avoids the excessive generation of heat, as itsuspends the carbid in thewater which absorbs the heat during generation. Thus the particles finally precipitated to the bottomare small enough-to pass through the dram gate 2.,

The valve 28 and its rod 25 and spring 26, provide an automaticcut ofi which prevents the falling of carbid into the ater during the filling of the holder 23.

What is claimed is: 7 1. An acetylene gas apparatus, including a generator, a buoyant bell'disposed therein, a car-bid holder carried by the bell, a screen to be submerged, and a combined sludge stirrer and support for said screen mounted for disposition-within the generator carried bodily with the bell. v I y 7 2. 2m acetylene gas apparatus, including a generator, a buoyantbell disposed therein,

a carbid holder carried by the bell, ascreen to be submerged, andha "combined sludge stlrrer and support'for said screen mountedfor disposition within' the generator carried bodily with the bell,.theconnection'between.

1 a carbidholder carried concentrically of the top ofthe bell,a s'creento be submerged, a support forsaid screen slidably connected to the bell for. disposition within the gen- I erator, the screen thereof being adapted to extend above the bottomiof the generator and in line to receive. the carbid emptied a generator, a buoyant bell disposed therein,

a carbid holdericarrie'd concentrically of the top oftthe bell, a screen to be submerged, I

a support for said screen slidably connected to the bell for disposition within the generator, the screen thereof being adapted to "extend above the bottom of the generator and in line to receive thecarbid emptied from'the holder, and a sludge stirrer also connected to and carried by the bell.

5. An acetylene gas apparatus, including a for movement below the rim thereof, into the generator, a sludge stirrer connected to the-lowerends ofthe rods for disposition uponthe bottom of the generator, a screen supportaconnected to and carried by the sludge'stirrer, and" a1 screen mounted in said support.

In testimony that I claim the foregoing as myown,-I have hereto alfixed mysignature in the; presence of two witnesses.
